IT managers and businesses looking to implement generative AI have discovered that research-augmented generation (RAG ) is a necessity. Enterprises can ground an LLM in enterprise data by using a large language model ( LLM) and RAG, which increases output accuracy.
But how does RAG job? What are some Fabric apply situations? And are there any actual choices?
Davor Bonaci, the CEO and executive vice president of collection and AI company DataStax, spoke with TechRepublic to learn more about how relational AI is being leveraged in the market as it becomes available in 2024 and what he anticipates the technology will look like in 2025.
What is Retrieval Augmented Generation?
RAG adds extended or augmented perspective from an business to enhance the importance and accuracy of relational AI LLM model outputs. It enables venture use cases for relational AI LLMs.
Bonaci explained that while LLMs have “basically been trained on all the data available on the internet”, up to a particular cut-off time, depending on the model, their vocabulary and basic awareness strengths are offset by major and well-known problems, such as AI hallucinations.

You may ground it in business data if you want to use it in an organization setting. Then, you get a lot of delusions”, he said. ” With RAG, instead of just asking the LLM to make things, you say,’ I want you to create something, but kindly consider these things that I know to be correct.'”
How does RAG function in an organization building?
RAG gives an LLM allusion to an organization data set, such as a information center, a database, or a file set. For example, DataStax’s primary product is its vectors database, Astra DB, which enterprises are using to help the creating of AI programs in enterprises.
A user’s keyword suggestions would typically move through a matrix research, which locates the most pertinent paperwork or pieces of information from a predetermined knowledge base. This could include enterprise documents, academic papers, or FAQs.
The retrieved information is then fed into the generative model as additional context alongside the original query, allowing the model to ground its response in real-world, up-to-date, or domain-specific knowledge. This grounding lowers the chance of hallucinations that could be bad for an organization.
How much does RAG make generative AI models ‘ output better?
“night and day” refers to the difference between using generative AI with and without RAG, according to Bonaci. For an enterprise, the propensity for an LLM to hallucinate essentially means they are “unusable” or only for very limited use cases. The RAG approach opens the door for generative AI in businesses.
” At the end of the day, they]LLMs] have knowledge from seeing things on the internet”, Bonaci explained. They will, however, give you a very confident response that may be completely incorrect if you ask a question that is kind of outside the left field.

According to Bonaci, RAG techniques can increase the accuracy of non-reasoning tasks ‘ LLM outputs to over 90 %, depending on the models and benchmarks used. For complex reasoning tasks, they are more likely to deliver between 70-80 % accuracy using RAG techniques.
What are some RAG use cases?
RAG is used across several typical generative AI use cases for organisations, including:
Automation
Enterprises can automate repeatable tasks by combining LLMs with RAG. A common use case for automation is customer support, where the system can be empowered to search documentation, provide answers, and take actions like canceling a ticket or making a purchase.
Personalisation
RAG can be used to synthesize and summarize a lot of data. Bonaci gave the example of customer reviews, which can be summarised in a personalised way that is relevant to the user’s context, such as their location, past purchases, or travel preferences.
Search
RAG can be applied to improve search results in an enterprise, making them more relevant and context-specific. Even if the search terms do n’t exactly match the available content, Bonaci noted how RAG assists streaming service users in finding movies or content that is relevant to their interests or location.
What applications do knowledge graphs have for RAG?
Using knowledge graphs with RAG is an “advanced version” of basic RAG. While a vector search in a basic RAG finds similarities between a vector database and is appropriate for general knowledge and natural language, Bonaci explained that it has limitations for specific enterprise use cases.
A customer inquiry, such as whether international roaming is included, would be required by the AI in a situation where a mobile phone provider offers multiple-tiered plans with varying inclusions. A knowledge graph can aid in arranging the information to identify what applies.

The conflict between the plan documents ‘ content and one another, according to Bonaci. ” So the system does n’t know which one is true. Therefore, you could use a knowledge graph to aid in conflict resolution and proper organization.
Are there any alternatives to RAG for enterprises?
A generative AI model can be fine tuned, which is the main alternative to RAG. Instead of acting as a prompt, enterprise data is fine tuned to create an influenced data set that can be used to prepare the model for use.
According to Bonaci, RAG has been the most popular method to date for advancing generative AI as a business priority.
” We do see people fine-tuning models, but it just solves a small niche of problems, and so it has not been widely accepted as a solution”, he said.
